Detailed Description
The invention will be described in further detail with reference to the drawings and the specific embodiments, it being understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
In the following description, suffixes such as "module", "component", or "unit" for representing elements are used only for facilitating the description of the present invention, and have no specific meaning per se. Thus, "module," "component," or "unit" may be used in combination.
In order to solve the problem that in the prior art, when the water replenishing tank is applied in a special environment and the inclination and the swing occur, the liquid level in the water replenishing tank is out of control, the embodiment of the invention provides the water replenishing tank, as shown in figure 1, which comprises a plurality of liquid level switches 1 and a controller 2,
the liquid level switch 1 is connected with the controller 2 and is used for detecting the liquid level of the water supplementing tank so as to determine the current liquid level state; wherein the liquid level state comprises an alarm state or a normal state;
and the controller 2 is used for determining a corresponding control strategy according to the liquid level states of the liquid level switches.
In this embodiment, the water replenishing tank includes a plurality of liquid level switches 1 and a controller 2, where the liquid level switches 1 are connected with the controller 2 and are used for detecting the liquid level of the water replenishing tank to determine the current liquid level state; wherein the liquid level state comprises an alarm state or a normal state; and the controller 2 is used for determining a corresponding control strategy according to the liquid level states of the liquid level switches 1. Therefore, the liquid level states of the liquid level switches 1 can be comprehensively considered, so that a corresponding control strategy is determined, when the water supplementing tank is inclined and swayed in any direction and at any angle, the liquid level runaway caused by misjudgment of the liquid level switches 1 under the inclined and swaying condition can be avoided, the liquid level in the water supplementing tank is ensured to be in a controllable state at all times, and the stable operation of all equipment in the system is ensured.
The water replenishing tank can be applied to an air conditioning system and a heating system, a boiler system and the like. When the water supplementing tank is positioned on the ship, the water supplementing tank can incline and swing along with the navigation of the ship, so that fluctuation of the liquid level is caused, and if only one liquid level switch 1 is arranged, the fluctuation of the liquid level can cause misjudgment of the liquid level switch. In one example, when the water replenishment tank is inclined leftwards along with navigation of the ship, the liquid level on the left side is higher, the liquid level on the right side is lower, and if the higher liquid level reaches a preset high liquid level value, the liquid level switch 1 sends a signal to the controller 2 so that the controller 2 controls the water replenishment tank to drain, but in reality, the water replenishment tank does not need to drain due to excessive water, but is misjudged by the liquid level switch 1. The embodiment of the invention can comprehensively consider the liquid level states of the liquid level switches 1, thereby ensuring that the liquid level in the water supplementing tank is in a controllable state at all times and ensuring the stable operation of all equipment in the system.
In one possible implementation, the liquid level switches 1 are arranged on two opposite side walls of the water supplementing tank in a scattered manner, and the positions of the liquid level switches 1 arranged on one side are higher than the positions of the liquid level switches 1 arranged on the opposite side.
In one possible implementation manner, the number of the liquid level switches 1 is plural, and as shown in fig. 2, when the liquid level switches 1 are floating ball liquid level switches, the number of the liquid level switches can be two, and the liquid level switches are respectively diagonally arranged on the liquid level surface of the water supplementing tank, so that the technical scheme of the invention can be realized. Because when the water supplementing tank swings obliquely towards any direction and any angle, the liquid level switch 1 can accurately determine the liquid level in the diagonal setting mode, so that the controller can accurately judge according to the liquid level state, the cost is reduced while the liquid level is prevented from being out of control, and the water supplementing tank is more economical and practical. The two float level switches shown in fig. 2 are respectively arranged at the diagonal angles of the surface of the water supplementing tank, and are marked as a float level switch 11 and a float level switch 12, when the water supplementing tank is inclined to the left side, the position of the float 3 of the float level switch 11 can rise, and the position of the float 3 of the float level switch 12 can fall. It is thus possible to determine that the water replenishment tank is in an inclined environment, and that replenishment or draining is not required.
Taking fig. 3 as an example, the working principle of the float level switch is briefly described, the float of the float level switch is subjected to the buoyancy of water, the change of the liquid level can lead to the change of the position of the float, when the float ascends or descends, the magnet in the float acts with the magnetic reed switch, and the magnetic reed switch can generate a switching value signal. In fig. 3, the reed switch is a limit block. And two stopper 4 in the upper of fig. 3 represent the preset high liquid level of floater liquid level switch, and two stopper 4 below represent the preset low liquid level of floater liquid level switch. The following implementation is specifically illustrated in the arrangement of fig. 3.
In one possible implementation manner, the liquid level switch 1 is further configured to determine that the current liquid level state is a high liquid level alarm state when the liquid level is greater than or equal to a preset high liquid level, and send a high liquid level alarm signal to the controller 2; when the liquid level is smaller than or equal to the preset low liquid level, determining that the current liquid level state is a low liquid level alarm state, and sending a low liquid level alarm signal to the controller 2. Wherein, the high liquid level alarm signal and the low liquid level alarm signal are both switching value signals. The liquid level switch 1 is further used for determining that the current liquid level state is a normal state when the liquid level is between a preset low liquid level and a preset high liquid level. The water replenishing tank further comprises: and the controller 2 is used for controlling the opening of the water drain valve when the liquid level states of the liquid level switches 1 are all in a high liquid level alarm state. The water replenishing tank further comprises: and the water supplementing pump is connected with the controller 2, and the controller 2 is used for controlling the water supplementing pump to be started when the liquid level states of the liquid level switches 1 are all in a low liquid level alarm state.
In this implementation, for example, in fig. 3, the float level switch may feed back the on-off signal to the controller, and the controller 2 may monitor the level of the water replenishing tank, so as to control the start or stop of the water draining valve and the water replenishing pump, and when the float level switch 11 and the float level switch 12 are both in the high level alarm state, the controller 2 controls the water draining valve to be opened. When the float level switch 11 and the float level switch 12 are in the low liquid level alarm state, the controller 2 controls the water supplementing pump to start to supplement water for the water supplementing tank.
When the two floating ball liquid level switches are in a high liquid level alarm state, the fact that the water quantity in the water supplementing tank is large (not caused by inclination and swing) is indicated, and therefore the water draining valve can be controlled to be opened for draining. When the two floating ball liquid level switches are in a low liquid level alarm state, the water quantity in the water supplementing tank is smaller (not caused by inclination and swing), so that the water supplementing pump can be controlled to be started for supplementing water, and the accurate control of the liquid level in the water supplementing tank can be realized.
In a possible implementation, the controller 2 is further configured to control the drain valve to close after a first preset time from when the plurality of liquid level switches 1 each exit the high liquid level alarm state during draining. The controller 2 is further configured to control the water replenishment pump to be turned off after a second preset time from when the plurality of liquid level switches 1 exit the low liquid level alarm state during the water replenishment process.
The first preset time and the second preset time can be determined through experiments, and it can be understood that when the liquid level switch 1 just exits from the liquid level alarm state, the liquid level switch can enter the liquid level alarm state again due to environmental change or water level fluctuation, so that the water drain valve or the water supplementing pump can be controlled to be closed after the preset time, the water drain valve and the water supplementing pump can be prevented from being frequently started, the energy waste is avoided, and the damage to the water drain valve and the water supplementing pump caused by frequent start and stop is avoided.
In a possible implementation manner, the water supplementing tank further comprises a prompting device, and the controller 2 is further used for controlling the water draining valve and the water supplementing pump to maintain the current state unchanged and controlling the prompting device to send prompting information when the liquid level state of at least one liquid level switch 1 is in a normal state; the controller 2 is further configured to control the water drain valve and the water replenishment pump to maintain a current state unchanged and control the prompting device to send prompting information when the liquid level state of the at least one liquid level switch 1 is a high liquid level alarm state and the liquid level state of the at least one liquid level switch 1 is a low liquid level alarm state, wherein the prompting information is used for prompting a user to determine inclination and swing conditions of the water replenishment tank and/or fault information of the liquid level switch.
Taking fig. 3 as an example, when a liquid level switch 1 is detected to be in a high liquid level alarm state and a liquid level switch 1 is detected to be in a low liquid level alarm state, or when a liquid level switch 1 is detected to be in an alarm state and a liquid level switch 1 is detected to be in a normal working state, a water drain valve and a water supplementing pump are controlled to maintain the current state unchanged, and an alarm is continuously given to remind a user to check whether the liquid level switch is caused by inclination and swing of a use environment or check whether the liquid level switch is in failure.
When the scene that this realization mode shows is that the moisturizing case takes place the slope, the liquid level state of liquid level switch 1, at this moment, need not to carry out moisturizing or sluicing, only need remind the user to look over the state of moisturizing case can. And it will be appreciated that when one of the level switches 1 is in a normal operating condition, i.e. no alarm signal is sent to the controller 2, the cause may also be that the level switch is damaged, whereby in this case the user may be prompted to see if the level switch is damaged.
The prompt message can be sent out by voice broadcasting, flashing of an indicator light and displaying of characters on a display.
